| For each plant, the coordinates along the axis of the stem and the midrib of each lamina were recorded. |
| Between the two crura of the fornix is a white, triangular lamina, known as the fornical commissure. |
| The cells were surrounded by a basal lamina and joined by primitive junctions. |
| Abundant basal lamina, interdigitating cell membrane, rough endoplasmic reticulum, and pinocytotic vesicles were seen in all 3 cases. |
| Posteriorly, the mesial lamina of the splenial is firmly sutured onto the anterior end of the prearticular. |
| The width of the fenestrated layer between the basement membrane and the cellular cortex of the lamina monopolar cells is reduced. |
